I know for a fact that 2 things in the Walmart ad are correct:
5' Nutcracker Assortment - $96.00
7' Pre-lit Slim Noble Christmas Tree - $39.00
These were both confirmed by my brother, who works in lawn & garden at Walmart. He said that his store actually got in trouble for accidentally placing the nutcracker figures out early and selling a couple for that price.
He wasn't sure about anything else, since he only works in lawn & garden - and he won't help me find out anything else.
